I disagree, I think it depends. We need to worry about getting the most wins possible this year, then worry about next year, next year. I wouldn't play him JUST so he gets more experience for next year, because that is giving up on this year. And I wouldn't redshirt him if he is the best JUST so he is still here 4 yrs from now, because that to is giving up on this year. Play the guy who gives you the best chance to beat Weber State. Then the next week, play the guy who gives you the best chance to beat Texas, etc.
ONLY if we are eliminated from postseason play and it becomes apparent that ACS would give us the best chance to win, would I consider changing that strategy. At that point I wouldn't see a reason to burn a redshirt if you KNOW you are not going bowlinG, but even then you could make the argument that the season is lost anyway, why not get him some experience. START THE GUY THAT GIVES YOU THE BEST CHANCE TO WIN YOUR NEXT GAME, WHOEVER IT IS.
